Materials & Care
Each Oia piece is crafted using a considered selection of materials, chosen for their durability, comfort, and purpose.
Our jewellery collection is made from:
- PVD-coated stainless steel, designed for everyday wear
- Gold-plated brass, used for bold, statement designs
- 925 sterling silver, Known for its luminous finish and lasting strength and comes in rhodium, gold-plated or vermeil finishes for investment pieces.
To keep your jewellery looking its best, we recommend a few simple precautions. Avoid wearing your necklace while swimming, showering, or exercising, and avoid prolonged exposure to chemicals, damp and humid environments. Water, sweat and chemicals can dull the finish or damage delicate stones and pearls. When you’re not showing off your piece, store it in your Oia pouch—this helps prevent scratches, tangling, and exposure to sunlight that can fade gemstones.
Every piece is thoughtfully designed to be worn and loved for years—whether you’re layering, gifting, or keeping it all for yourself. With a little care, your necklace will maintain its shine and beauty for years to come.
